Apinicafio'n med Vmy 1a,

To all whom z'tgnay. concern.' l

Be it known that I, VrLLrAM RowLAND E DWARDs, a subject of the. King of Great Britain, of 24 Upper Bedford Place, London, England, have invented a certain new and useful, Improvementina Nonspillable Boxer Container, Such as vThose Used for LElect ic Accumulators or the like, of which the following is a specilication.

This invention relates to nonespillable yboxes or containers for electric batteries or accurmilators, and the ,invention has'for -`its object toiprovide an iinprovecl`rneans for venting the same. y

According to thepresent inver-itfion avent in the top of the box .or cell is adapted to be openedand closedby a rod'so'arranged fand iitted as to be `pressed upwards and open the vent when vthe box is resting'on its support .and to protrude from the bottom-of the Abox and close the vent when the box 'sereral Ways 0f in Fig. 1'.

is raised from its support.' d 1 The saidl rod is preferably mountedin a tube passing through thegbox from top*V to bottom and is pressed downward by a suit- 'abilerrng- Y 'The Avent may leither befformeduponthe end yof the rod or it be placed to one side of .the through tube and rod's'o-as toy b' opened and closedby a suitable connectionrom the head of the rod. f

i The accompanying', drawings illustrate carrying outv this invenl is a sectional elevation showing oneconstruction, Y l' ili'g, 2 is a similar View showing another 'coilstructom odifications Vof the construction shown Figs. 5 and 6 are sectional eleva-tions. showing twofurther Amodrtications- Fig. .Tis a sectional elevation Ashowing the 'constructionA of an outer 'case for the bat tery when used lfor aerolzilanes.V v y In the construction' shown A'in-Fig. 1 the box or container a isitte-d with va straight tube b passing through the boxf'from 'top to bottom, and in this tube is mounted a l through rod-c.- In-the'top' "of thebox'fa at a short distance-from thetube o and rod 0 I litf another; short venting tuberi which passes into the boxand extends short distance above the top or cover. The upper end of the rod cV is formed with a head F'gs. 8 and l are detail views showingl 1923. serial No. 651.320.

adapted to bear against a resilient-leverorv i .bearer plate e lof ebonite or'othersuitable material, the other.,r end ofwhich is` fixed' to the top of theboxas at f. Ihe said lever e passes over the top of the vent tube d and is fitted with a disc of rubber orother suitable material g which when presseddown upon th-e aperture of the vent-d will closeV edges of the said tubearebevelledoi'f'to` form la good 'jointf with the closing disc It` will be seen that when the lbatterybox a is lifted or tilted the resilientleverle will press the through rodcdownwards so as to protrude from the *bottom of the box,I and will' also' keep the rubber disc g ftightly pressed down on the top ofthe shortuvent ltube d whilst -whenthe boxis' on theground the through rod being, pressed upwards against thej lever e the latteriwilltbe'raised Vand the rubber disc g lifted olf` the 'topof vthe venting tube' d allowing the escape of fumes from the box. f f

4In the construction shown in' Fig. '2,f'1the lower end ofthe through tube'E isv enlarged to form Ia recess'bin whfi-chfis mountedva spring YL Vsurrounding! the lower lend fiof; the `Urod-0VVV and bearing agai'nstrthene'nd of/the recess "Ybfat-one endwhilst the other bea-rs upon -an adjustable nut or colla-r' e 'on/the vlower eind of the'rodwvhich` projects a suitable dist-ance fromtherecessf In this Iconstruction lthe upper end of the rod cis directly connected to the -lever '6.4.

In the modiication'shown in Fig.f3,the

lever e is held down by a'spring which l serves-to operatethe rod "of and in Fig'g '4: the

rod c Vpasses through the endof-the` lever e Vand/bears :against a .spring jwhi`ch1sur rounds theupper-end ottherod and is'sup- Aported-byv a bridge piece cthrough which the upper end of the said rod passesw w vIn the further modified 'constructions ioo shown in Fig.- 5 the venting-device. ispl'aced and down in the tube b. f1.; The rod c is enlarged and?made"tubular at its top end as atc so as to 'lit closely into :ai correspondingly enlarged end Z22 of the tube b. 5

in alignment with the rod c whichslides up Holes b3 are made in the tube and corresponding holes c3 are also made in the tubular end of the rod ci the arrangement of which holes is such that when opposite each other there will be a clear passage left for any fumes or gas to pass from inside the battery box to the atmosphere. The top of the said tubular part of the rod is either left open or perforated.

In the drawing the tube is shown as extended above the top of the box ai and cove-red by a perforated cap Z and the spring L for pressing the rod c downwards is enclosed between the said cap Z and the base of the tubular part c ofthe rod.

v The rod c may have a collar or washer of suitable material fitted near the top and below the tubular part to prevent any moisture that may accumulate from running ldown the tube.

In operation, when the box a rests upon its support tlierod c is pressed upwards and the holes b3 and c3 come opposite each other and a. clear opening` is left from the inside ofthe box to the atmosphere and when the boxz is lifted the spring 7L will push the rod c downwards. The tubular parts of the rodV c will slide endwise in the enlarged end b2 of the tube Y) and close the venting holes b3 and thus prevent any liquid or fumes from passing out of the box.

Y Fig. 6 shows a modification of Fig. 5 wherein the spring for pressing the rod c downwards is mounted in a recess b at the lower end of the tube in a similar manner to'Fig. 2, but in this arrangement the upper end of the rod c carries ai coned head m seated so as to cover the holes b3 in a coned 1rWith the arrangements shown in Figs. 5 and 6, the tube l) may be filled with vaseline or other lubricating material to facilitate the. sliding movement of the rod o which material will also prevent moisture from passing down the tube l).

For use in aeroplanes oriwhere the bat-- 'tery is likely to be used in an inverted position I mayV employ an outer casing n of suitable material as shown vin Fig. 7, the

f sides and ends of t-he said outer casing n being inclinedv outwardly and upwardly so that when the casing is tilted to any considerable angle, the accumulator will also tilt sufiiciently as shown in dotted lines to allow the rod c to operate.

The top of the outer case n is suitably ventilated and placed so close to the accumulator as to ensure that the latter always recumula'tors comprising a vent in the top of the box or cell adapted to be opened and closed through the medium of a rod so arranged and fitted as to be pressed upward and open the vent when the box is resting on its support.

2. Improved means for venting containers for electric batteries comprising t-he combination with a battery container of a vent in the top thereof, a vertically slideab-le rod carried by said container and projecting`A`m beyond the base thereof, resilient means for pressing said rod downwards and causing the lower end to protrude beyond the bottom of the container, means whereby the said vent is opened by the rod when the protrud-vk ing end thereof is pressed upward by the container resting on its support and whereby said vent is closed by said rod protruding from the bottom of the container` when the latter is raised from its support.

3. Improved means for venting containers" for electric batteries comprising the combination with a battery container of a tube passing through said container from top to bottom, a rod slideably mounted in said tube, a vent mounted in the to of the container to one side of the slidea ly operating rod, a cap for opening and closing said vent, a lever carrying' said cap and operatively connected with the top of said rod, resilient means for pressing said rod downwards so that its lower end protrudes beyond the base of the container and closes the vent when the container is raised from its support and whereby said rod ispu-shed upwards and...

opens the vent when the container is from its support. n Y 4.
